Improvement in machines for bending wire



r UNITD STATES l T0 @ZZ `ul/1.0704) t may concern: y Be `it known that I, N. C. PERRY, of the i town of Chester, Middlesex county, andState of Connecticut, have invented certain new and useful Improvements in Machines for Bending 'Wire5 and Idoherebyl declare that the following is a full and exactdescription thereof,` reference beinghad to the accompanyingdrawt ings, and to the letters of reference marked thereon.

` Thelettei-Ain the annexed drawings, which make a part of this specification, represents a cylinderof iron` with a wheel at the bottom to which it is attached, and another at top, the `whole being of spool-like form. B is" a clamp,` having near the lower end a hole through which the pivot D is made to a pass, so thatthe clamp at its upper end `may move backward `or forward through a mortise formed to receive'it in the upper wheel. This mortiseis `made sufficiently long to admit a key behind the"` clamp, the key being tapering, `so as `to adjust the clamp exactly to suit the ofceithasto perform.` 'y

E represents the handle or, lever by which `handle is a ilat enlargement, of a circular form, and plays upona pivotpassing through `its center, `being kept in its place by the disk Y F, which constitutes the `upper part of the Vthe machine isoperated. `The end of this PATENT FFICE. y

pivot. The lower `end ofthe pivot extends down into the cylinder, and is kept in its 'place by the screw G. Near the edge of the disk F is the eccentric-post H, around which the wire is bent. On the top of the handle is screwed the guide` I, with a wedgelike end extending nearlyl to the post H, and having a notch cut in it to hold the wire in proper position for bending it.

The great advantage of the eccentric-post is in the gain of leverage. Vere the post placed in the center of the disk and the guide I operating in close proximity to it, the bend ing of large wire would become difficult, if not impossible, whereas by the eccentric position of the post and the consequent eccentric motion of the guide around it, the work is effectually and beautifully performed.V

What I. claim` as Inyinvention, and desire to secure by\Letters Patent, is-

1. The use of the eccentric-post H, in the manner and for the purpose set forth and described. i

2. The guide I and the clamp B, in-combination with the eccentric-post H, operated in the manner herein set forth and described.
